Title
(EN) WATER TREATMENT METHOD FOR SIMULTANEOUS ABATEMENT OF CARBON, NITROGEN AND PHOSPHORUS, IMPLEMENTED IN A SEQUENCING BATCH MOVING BED BIOFILM REACTOR
(FR) PROCEDE DE TRAITEMENT DES EAUX POUR L'ABATTEMENT SIMULTANE DU CARBONE, DE L'AZOTE ET DU PHOSPHORE, MIS EN ŒUVRE DANS UN REACTEUR A FILM BIOLOGIQUE A LIT MOBILE EN MODE SEQUENTIEL DISCONTINU
Abstract
(EN)
Water treatment method for simultaneous abatement of carbon, nitrogen and phosphorus, implemented in a sequencing batch moving bed biofilm reactor (SBMBBR) comprising supports suitable for the development of a biofilm. The method comprises sequences of successive treatments, each treatment sequence comprising: an initial phase of anaerobic treatment, said initial phase of anaerobic treatment being followed by at least one aerobic/anoxic cycle consisting of: an aerobic treatment phase so as to obtain an ammonium ion concentration that does not pass below a threshold concentration of ammonium ions; and, a phase in which the biofilm is placed, at least locally, under anoxic conditions, this phase being concomitant with or posterior to said aerobic treatment phase; the threshold concentration of ammonium ions being calculated to allow the development of anammox microorganisms during the phase in which the biofilm is placed, at least locally, under anoxic conditions.

Le procédé comprend des séquences de traitements successifs, chaque séquence de traitement comprenant: une phase initiale de traitement anaérobie, ladite phase initiale de traitement anaérobie étant suivie par au moins un cycle aérobie/anoxie constitué de : une phase de traitement aérobie de telle sorte à obtenir une concentration en ions ammonium ne passant pas en-dessous d'une concentration seuil en ions ammonium; et, une phase dans laquelle le film biologique est mis, au moins localement, en conditions anoxiques, cette phase étant concomitante ou postérieure à ladite phase de traitement aérobie; la concentration seuil en ions ammonium étant calculée pour permettre le développement de micro-organismes anammox pendant la phase dans laquelle le film biologique est mis, au moins localement, en conditions anoxiques.
